Tromler - Actiroll and Actiroll HD/HDC Rollers

• Mechanical weight distribution system ‘’Contoura’’on Actiroll and hydraulic one on Actiroll HD. 
• Homogeneous weight transfer on the whole working width  (33% on each disc gang instead of 25%/50%/25%).
• Each roller section works independently ensuring optimal soil contact  along the whole working width .
• Two springs located on each extension equally transfer the load onto the wings (for Actiroll 6.30m to 8.30m). With the Actiroll 9.30m as well as with the Actiroll HD/HDC (9.50m, 10.30m and 12.30m) the load is transferred by two hydraulic cylinders and one accumulator. 

• The exceptional cast quality and special design used for the rings allows us to extend the warranty time to 3 years on Crosskill and Cracker rings. Up to 6 years on Cambridge Stone Ring. They are assembled onto a heat treated shaft (ø 60mm), maintained on each side by strong bearings.
• The adjustment of the rings gap is made by simple end stops located on each side of the gang. This adjustment can be made without any dismantling

Cambridge ø 500mm
Ideal for ballasting young plants (for a better contact between the roots and the soil and increase the sucking). Can be used after ploughing as well (with Clod Board)  or after a prepared field. Good auto-cleaning effect.

Cambridge ø 550mm (from 5.30m classic up to 24.30m):
Same function - used for heavy soils

Cambridge ø 600mm (from 6.30m to 16.30m):
Same function - used for heavy soils

Crosskill ø 530 mm (whole range) and heavy Crosskill ø 600 mm on Actiroll HD/HDC only

For tough clods and stony conditions, good auto-cleaning effect in wet conditions because of the ring diameter difference

Cracker ø500mm/ ø550mm
These rings are able to run cleaner due to the movement of each ring. They also apply a downforce for a better contact of the seeds to the soil. The result is a loose top layer that prevents capping and underneath firm layers for a better root development. In combination with a cracker board, these rings are ideal for seedbed preparation, to fight against weevil on maize stalks as its habitat for hibernation is destroyed. They also support the tillering of grass and seed germination thanks to a better seed-to-soil contact

• With the Clod Board, the Actiroll is an active soil preparation tool, able to combine levelling and cracking in one pass, due to the high vibrations of the cracker tines.
• The position of the Clod Board can be hydraulically adjusted from the cab. For rolling winter crops or grass fields, the Clod Board can be easily set into off position.

• The wing sections are mechanically locked. They also lock the cylinder of the transport carriage for utmost security. Moreover the Actiroll HD and HDC run very smoothly due to their low centre of gravity.
• Transport width in between 2.50m and 3 m depending on the diameter of the rings 
• Compact machine and good maneuverability
